WINDOW REPLACEMENT L-INIT Filed Dec. 9, 1960 's Sheets-Sheet 2 Zn n- Rfuchin Inventor By Attorney 3 Sheets-Sheet 3 Filed Dec. 9, 1960 Inventor Zon Ruchin Attorney United States Patent WINDOW REPLACEMENT UNIT Zan Ruchin, E. 41st St., Bayonne, NJ. Filed Dec. 9, 1960, Ser. No. 74,902 1 Claim. (Cl. 16-197) This invention relates to a window unit which is designed to be inserted into a window frame as a replacementfor a window to be removed. More specifically, it deals with a window replacement unit in which the sashes may be tilted inwardly out of the unit to provide ready access thereto for cleaning, glazing, and the like. Further features include novel balancing sash carriers, sash guides, and other window members.

The replacement of old or damaged windows is, generally, a tedious undertaking, involving the fitting into the frame of awindow of the type being replaced. If new features are to be adapted, such as replacement of sash balances for sash weights, and the like, a major surgery? project is involved with respect to the frame.

By means of .the present invention, a superior window and sash bala'ncing device. may be substituted simply by removing the inner molding and inserting the unit of the present invention into the space formerly occupied by the old window sash. The old sash weight housing and other appurtenances need not be disturbed in the operation, and a superior installation is possible in the matter of a few minutes.

The invention will be more readily understood by reference to the accompanying drawings. FIGURE 1 illustrates a front (inside) view of a preferred embodiment of a replacement window unit. A cross-sectional side view thereof, taken through the vertical center of FIGURE 1, is presented in FIGURE 2. FIGURE 4 presents an isometric view of a side channel guide with a clutch member in place, while FIGURE 7 depicts an isometric view of the clutch attached to the bottom of the sash. This attachment serves also as a center around which the sash is pivoted out. The side channel guide serves also to house the spring sash balancing unit, a cutaway side view of which is illustrated in FIGURE 8. FIGURES 3 and 5 are cross-sectional views of the side channel guides, with most of the sashes cut away. FIG- URE 3 is a section cut horizontally through the channel and bottom of the clutch, looking down, with the lower sash pivoted out. FIGURE 5 is a section cut horizontally through the channel but with the clutch left intact, looking up and with the lower sash replaced. A crosssectional side view of the replacement window unit with sashes pivoted out and clutches and spring balancing units in place in the channel guides is shown in FIG- URE 6. Similar numerals refer to similar parts in the various figures.

FIGURES 3 and 5 are, to all intents and purposes,

identical, though mirror images of each other, except 0 that FIGURE 3 is a cross-section viewed from above, and FIGURE 5 is a cross-section viewed from below, through different sections of the clutch. Also, in FIGURE 3, the sash Sa is shown pivoted out, and in FIGURE 5, sash Sb is shown snapped back into position in the unit. Allusions may be made, intermittently, toeither figure, depending on which is expected to yield a clearer image in the mind of the reader.

Referring again to the drawings, the window replacement unit is designated generally as numeral 10, the top section as 2, the sides as 3, and the bottom as 4, all of which are attached to each other by screws, shown at the top, only, as 1. All the above elements are made of aluminum.

Channel member '0, FIGURE 4, comprises a multichannel extrusion, preferably of aluminum, wherein the ICQ front, or inner channel 6, is provided with a flange 7 partial-ly closing the channel opening. It will be noted that forwardly projecting flange 7a. extends laterally a little more towards the sash Sa, FIGURE 3, than edge 8a of channel side 8, thereby allowing lip 9a of weather stripping 9 attached to side Sb of sash Sa to clear edge 8a and seal against flange 7a. Thus, as sash Sa is swung out on pivoting angle member 15, FIGURE 5, weather stripping 9 of sash Sb clears channel edge 8a. The inner space 6 of channel C, FIGURE-4, is utilized for housing the balancing spring assembly unit, FIGURE 8, and clutch member 13, FIGURES 4 and 7, to which sash S is pivotally attached, as already outlined.

i Inner channel 6, FIGURE 4, is attached by means of connecting strip 7 to outer channel 12 also carrying a flange 11 which partially closes the channel and extends laterally towards sash S, FIGURE 3, farther than the forward channel edge 7b so as to enable lip 9b of weather stripping 9 of sash S to form a seal and to allow sash S to be pivoted and clear the rest of the multichannel unit C. Channel 12 serves also to house a spring sash balancing unit, FIGURE 8, and clutch member 13, FIGURES 4 and 7, to which sash S is pivotally attached in the same manner as is sash Sa.

Guide locks 5, FIGURES 1, 2, and 6, attached to the upper edges of sash members S and Sa, respectively, comprise a housing holding spring-loaded pins riding in the channel hon-sings, 6 and 12, respectively, C, FIGURE 4. When the window panes are to be cleaned, for example, pin heads 5b are pulled back, thereby freeing the pins from engagement with the channel edges, and the sashes then may be pivoted inwardly, as in FIGURE 6, since they swing on their respective pivots, 15. After cleaning, the sashes may be pivoted back into place and pins 5 snapped back into their respective channels. As shown in FIGURE 2, pin housing 5 on upper sash Sa is concealed behind a small wooden strip 16 which serves as a weather stripping means. It will be noted, also, that bottom 4, FIGURE 2, of the window unit is preferably made of sheet aluminum, and is provided with a draining angle so that it fits snugly when fitted into a frame.

The clutch and bracket assembly, FIGURE 7, is composed of a strip of aluminum 13, bent into an inverted V shape. On its outer edges are cemented strips of a lamihated plastic 17, such as Formica, to provide smooth riding within channels adapted for this type of clutch. To produce changes in tension, screw 18 carries a spring 20 which is forced against the inner wall of the clutch. Turning the nut 19 changes the tension on the spring. Washer 21 is interposed between nut 19 and spring 20.

The clutch is attached to the bottom of a sash S on its outer edge by means of a bracket 22 and held in place with a screw 23 passing through a washer 24. The bracket is attached to the bottom of the clutch, bent at right angles to receive it, by means of a rivet 25.

The spring assembly, which is the heart of the balancing unit, is comprised generally of two coiled springs and two tubes, each riding alternately within the other. The outer tube 26 carries within itself a coiled spring 27, the upper terminal of which ends in a loop 27a which is engaged by a screw 28 passing through the upper terminus of tube 26. The lower end of spring 27 is clamped tightly about a short collar 29, which is in turn clamped tightly about an inner tube 30. This tube extends up to within a short distance of the top of spring 27. Within tube 30 rides another spring 31, the upper end of which, 31a, is booked through a hole in the upper end of tube 36. The lower end of spring 31 protrudes through tube 30 and ends in a hook 31b, and passes through two holes bored in the upper curve of clutch 13. The clutch and bracket assembly FIGURE 7, and spring assembly FIG- 3 URE 8 comprise the balancing unit which keeps the sash suspended at any position in the window replacement unit. The tubes and collar of the spring assembly are best constructed of brass and the springs of hard drawn steel wire.

The action of the spring balancing unit may be likened to the action of a pulley. When sash S is pulled down, the clutch and bracket assembly FIGURE 7, draws down spring 31 which is attached at 31a to the top of tube 30 and pulls it down. Tube 30, attached to the bottom of spring 27 by means of collar 29, pulls down spring 27 which is anchored at its upper end around screw 28 Which is attached to the top of tube 26'. The complete spring assembly is screwed into place by means of screw 28 to the top of the channel and into the frame fitted to receive the window replacement unit. The use of this spring balance, in conjunction with the clutch assembly, results in smooth action, requiring little efiort to manipulate the sashes.

The above description is presented as an embodiment of the invention. Component elements, therein, may be substituted by other elements which may perform substantially similar functions. These elements may now be in use or previously invented but may be considered as being within the scope of the appended claim.

I claim:

A spring-loaded balancing sash unit comprising a tube within which a coiled spring is suspended, at its upper end, by a screw passing through the upper end of the tube, and clamped at its lower end to a narrower tube passing through said spring, by means of a collar, the top of the latter tube being attached to another coiled spring of lesser diameter passing through it, and hooked to its upper end, and terminating in a hook at its lower end which is attached to the upper end of an inverted V clutch, said clutch being properly tensioned by a spring within its upper section, and having plastic strips cemented to its outer surfaces, and is adapted to be attached at its right-angled end to the bottom and outer edge of a sash by means of a bracket assembly.
